There is absolutely no reason whatsoever for C&D not to select the Peugeot 508 sedan as a basis for a mid size car in the US. It is not rocket science to re engineer that to meet local regs, nor would it be that difficult to fit an US compliant powertrain in it. Things may well move rapidly once the dust settles but one thing is clear, there will be wide scale pruning of platforms, components and powertrains in the very near future. In Europe, the use of FCA gas powertrains across the board is expected as the PSA range is getting long in the tooth and is not in any way cohesive. Not so clear cut regarding diesel, if they bother even.
